Take five radically different groups of people. The groups may radically differ in the usual categories (such as size, shape, color) or others (such as surface area, scent, hair texture, politics, emotional predicaments). Lead them by the hand, and then let go and give them a choice: field of flowers, field of gold, field of dreams, field of vision, field of applicants, filed of corn, field of bicycles, field of bicycles.
